Liquid retarder that can be added to acrylic colours to prolong drying time of the paint film.
For best results add 10-20% retarder acrylic colour. Mix thoroughly before painting.
The retarder keeps the paint film “open” and workable for a longer period
(typically 20-30 minutes at 10% concentration, depending on atmospheric conditions).
Over use may leave the paint film water-receptive in the long term: use
with care. Can be diluted with water if required. Clean brushes, tools, etc with water.
